Abstract
An axial flux electric machine comprises a rotor assembly configured to rotate about an axis of rotation. A stator core is coupled to the rotor assembly. The stator core comprises a stator core base and a plurality of circumferentially-spaced stator teeth extending from the base in a direction parallel to the axis. Each stator tooth of the plurality of stator teeth comprises a top surface, a pair of opposing circumferential sides, and a chamfered portion defined at an intersection of the top surface and each of the pair of opposing sides. The chamfered portion facilitates reducing an amount of torque ripple produced by the axial flux electric motor.
